Description of first aid measures
If inhaledMove the victim into fresh air. If breathing is difficult, give oxygen. If not breathing, give artificial respiration and consult a doctor immediately. Do not use mouth to mouth resuscitation if the victim ingested or inhaled the chemical.
Take off contaminated clothing immediately. Wash off with soap and plenty of water. Consult a doctor.
Rinse with pure water for at least 15 minutes. Consult a doctor.
Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.
Most important symptoms and effects, both acute and delayed
SYMPTOMS: Symptoms of exposure to this compound via ingestion may include sleepiness, mental confusion, unsteadiness, coma, slow and shallow respiration flaccid muscles, hypotension, cyanosis, hypothermia or hyperthermia, absent reflexes, painful gums and excessive fatigue. Other symptoms of exposure through ingestion may include ataxia, vertigo, nausea, anorexia, vomiting, hyperirritability, emotional disturbances, sexual impotency, diplopia, nystagmus, morbilliform skin eruptions and possible megaloblastic anemia. Ingestion may also lead to sedation, dizziness, an acute feeling of intoxication, maculopapular rash, leukopenia, thrombocytopenia, systemic lupus erythematosus, lymphadenopathy, acute psychotic reactions, hemorrhagic disease in the neonate and osteomalacia. It can cause mental dullness, drooping of the eyelids and, rarely, blurred and narrow vision. It can also cause a coma, the duration of which is dependent on the dose. If the coma continues, moist rales are heard in the lower lung fields, indicating pulmonary edema. Atelectasis or aspiration pneumonia with signs of lung consolidation and fever can also occur. Carbon dioxide retention under these conditions causes acidosis. Death occurs most often from pneumonia, pulmonary edema or refractory hypotension. Cerebral edema contributes to the persistence of coma. Chronic symptoms of ingestion include skin rash, mental confusion, drowsiness, hangover, emotional lability or depression, irritability, poor judgment, neglect of personal appearance and other behavior disturbances. Other symptoms may include general malaise, polyuria, thyroid enlargement, epidermal necrolysis, tremors, central nervous system depression, disequilibrium, personality changes, thirst and impaired sexual function. ACUTE/CHRONIC HAZARDS: When heated to decomposition this compound emits toxic fumes of nitrogen oxides. (NTP, 1992)
Indication of any immediate medical attention and special treatment needed
Treatment is supportive and symptomatic. The use of gastric lavage, activated charcoal, and cathartics has not been studied. Stabilization comprises the following measures: 1. Maintenance of airway, breathing, and circulatory integrity. 2. Endotracheal intubation as needed. 3. Assisted ventilation as required.
Extinguishing media
Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992)
Specific Hazards Arising from the Chemical
Flash point data for this chemical are not available; however, it is probably combustible. (NTP, 1992)
Advice for firefighters
Wear self-contained breathing apparatus for firefighting if necessary.
NFPA 704
| HEALTH | 2 | Intense or continued but not chronic exposure could cause temporary incapacitation or possible residual injury (e.g. diethyl ether, ammonium phosphate, iodine) | |
| FIRE | 0 | Materials that will not burn under typical fire conditions, including intrinsically noncombustible materials such as concrete, stone, and sand. Materials that will not burn in air when exposed to a temperature of 820 °C (1,500 °F) for a period of 5 minutes.(e.g. Carbon tetrachloride) | |
| REACT | 0 | Normally stable, even under fire exposure conditions, and is not reactive with water (e.g. helium,N2) | |

Personal precautions, protective equipment and emergency procedures
Avoid dust formation. Avoid breathing mist, gas or vapours.Avoid contacting with skin and eye. Use personal protective equipment.Wear chemical impermeable gloves. Ensure adequate ventilation.Remove all sources of ignition. Evacuate personnel to safe areas.Keep people away from and upwind of spill/leak.
Environmental precautions
Prevent further spillage or leakage if it is safe to do so. Do not let the chemical enter drains. Discharge into the environment must be avoided.
Methods and materials for containment and cleaning up
Collect and arrange disposal. Keep the chemical in suitable and closed containers for disposal. Remove all sources of ignition. Use spark-proof tools and explosion-proof equipment. Adhered or collected material should be promptly disposed of, in accordance with appropriate laws and regulations.
Precautions for safe handling
Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
Store below 40 deg C (104 deg F), preferably between 15 and 30 deg C (59 and 86 deg F), unless otherwise specified by manufacturer. Store in a tight, light-resistant container. Protect from freezing. Primidone Oral Suspension USP

Exposure controls
Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Set up emergency exits and the risk-elimination area.
Individual protection measures
Eye/face protectionWear tightly fitting safety goggles with side-shields conforming to EN 166(EU) or NIOSH (US).
Wear fire/flame resistant and impervious clothing. Handle with gloves. Gloves must be inspected prior to use. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.
If the exposure limits are exceeded, irritation or other symptoms are experienced, use a full-face respirator.
